Fabrics protect from chemical warfare agents

April 22nd, 2019 / By: / What's New?

A new coating for textile fibers shows promise for efficiently capturing toxic industrial chemicals and chemical warfare agents under real-world conditions, including high humidity. The research could lead to improved masks and personal protective equipment for soldiers and others at risk of exposure.

Researchers at North Carolina State University (NC State) and the U.S. Army’s Combat Capabilities Development Command Chemical Biological Center (CCDC CBC) have developed functional textiles that neutralized a blistering agent simulant under conditions of 80 percent relative humidity. The new coating also captured ammonia gas, a commonly produced industrial chemical in the U.S.

“For more than a century, we’ve had threats from chemical warfare agents, from chlorine and mustard gas in World War I to recent attacks against civilians in Syria,” says Dennis T. Lee, a recent Ph.D. recipient at NC State and lead author of an article about the work. “We need to find ways to capture and chemically break down toxic gases for practical, better-performing protective equipment.”

Future plans call for testing the new materials with real chemical warfare agents, working with U.S. Army experts at the CCDC CBC.

More details about this breakthrough development will be available in a feature about protective products for the Military that will be posted in early May on this site. The article, “Water-Stable Chemical-Protective Textiles via Euhedral Surface-Oriented 2-D Cu-TCPP Metal-Organic Frameworks,” is published in the journal Small.
